Title: Optical temp. measurement of continuously cast ingots - using annular gas jet to surround optical path and remove interference
IPC: G01J5/04
Filed: 1975-11-21
Abstract: A visual instrument (e.g. an optical pyrometer) is used for measuring the temp. of a body where the optical path is surrounded by a protective tubular sheath; which is extended by a cylindrical or diverging annulus of gas completely surrounding the optical path of the body. Gas is pref. also blown down the sheath to remove any interfering vapours. The device is for use on continuously-cast ingots, the flow of gas being sufficient to blow away water-spray interfering with temp. measurement, plus any dust and smoke, without affecting the temp. of the ingot-surface being measured. The gas used is pref. air, N2 and/or an inert gas, completely free from oil, CO, CO2 and H2O.

Title: Separating a gas from a gas and liquid mixture - esp air and water in a central heating installation
IPC: F24D3/10
Filed: 1976-06-02
Abstract: A method of separating a gas from a mixture of the gas and a liquid more dense than the gas, in particular, of separating the air from the water in a central heating system, consists in projecting the air/water mixture as a jet continuously against a surface inside a chamber. The jet and the surface are arranged at right angles to each other and in such a manner that the mixture spreads itself over the surface on impact, so that whilst the air rises towards a vent, the liquid falls and is drain off from below. The path followed by the jets sets up whirls and bubbles in the chamber at a lower pressure than that of the water spreading over the chamber wall, and air is thus drawn towards the zones of lower pressure before being evacuated. Method prevents the accumulation of air in the system, and eliminates the possibility under any circumstances, of blockage by steam or pumping back, of the feed water pipe.

Patent FR-2336538-A1 (FR)
Inventor: HOLET KENNETH MICHAEL
IPC: F25C5/00
Filed: 1976-12-17
Abstract: A device for controlling the opening and closing movement of a duct seal door of an automatic ice maker which requires a regulator for slowing down the closing of the door. The movement of the door about its rotational axis is transmitted via connecting linkages to the closure regulator which comprises a rotor positioned within a stator housing. The rotor's movement is coupled to the connecting linkages via a one-way clutch which decouples the rotor when the door is being opened, and causes positive coupling therebetween when the door is being closed. Disposed within the stator housing in a fixed-volume compartment is a viscous fluid, such as silicone gum. The rotor and stator include opposed rippled surfaces between which the viscous fluid is coactively disposed. The fluid acts as an impedance to the motion of the rotor, which motion occurs only upon the closing of the door, to thereby provide a controlled slow closure thereof.
